The inclusion complexes of a series of organometallic compounds- and aromatic compounds- have been studied by cyclic voltammetry using glassy carbon electrode for expanding the potential window. The variation of peak potential and peak current has been showed on cyclic voltammogram when the electroactive guest mols. are complexed with cyclodextrin. Dissociation constants of cyclodextrin inclusion complexes have been calculated on the basis of this variation by both the potential and current methods. According to the magnitude of dissociation constants, the relationship between the stability of cyclodextrin inclusion complexes and degree of matching host mol. with guest mol. has been discussed.
